How can you use “ros” in a sentence? Here are some example sentences to help you improve your vocabulary:
Interestingly it has been demonstrated that rapid production of ROS in endothelial cells exposed to TNFα is mediated by ceramide [ 32 ] . Ceramide is a central figure in the sphingomyelin pathway, which has also been linked to stress related signaling and apoptosis [ 33 34 ] . This report provides evidence that cytokines regulate the fate of CLENDO cells.
Abscisic acid response elements (ABREs) are important during the plant's response to abiotic stresses such as dehydration, salinity and cold, all of which are ABA-mediated [ 82 83 ] . There is evidence that ROS are involved in ABA signaling [ 84 ] . The enrichment of the ABRE motif in the promoter sequences of the genes in the stress cDNA collection may reflect crosstalk among stress signaling pathways mediated by common second messengers, such as H 2 O 2 . The over-representation of the SA-inducible element in the promoter sequences of the genes in the stress cDNA collection, especially those in the SA library, further validates the enrichment of the stressor-specific genes using the SSH technique and suggests that these genes may be regulated by the changes in the levels of SA that occurs in stress responses [ 85 ] .
1ACh, acetylcholine; ARF, ADP-ribosylation factor; DAG, diacylglycerol; G3PDH, glyceraldehyde 3-phosphate dehydrogenase; MAChR, muscarinic acetylcholine receptor; PA, phosphatidic acid; PC, phosphatidylcholine; PIP 2 , phosphatidylinositol 4, 5-bisphosphate; PKC, protein kinase C; PLD, phospholipase D; PMA, phorbol 12-myristate 13-acetate; PP, phosphatidylpropanol; ROS, reactive oxygen species; TLC, thin layer chromatography.
The second set of observations indicate that reactive oxygen species (ROS) activate PLD2 in a PKC-dependent manner [ 9 ] . There is much evidence that ROS generation is upregulated in AD brain [ 42 ] . Thus, it is possible that PLD2 may be activated in this disease resulting, perhaps, in dysregulation of PC metabolism.
The endothelial cell lining of the blood vessel is extremely sensitive to damage from reactive oxygen species (ROS), the results of which are losses of both microvascular metabolic function and barrier properties [ 46].
